A rebel at heart, the mom-of-four has refused to comply with the norm when it comes to her music, behaviour or even her sense of style.

Making her way through New York's JFK airport on Monday, the Vogue hitmaker donned top-to-toe black - including fingerless leather gloves with cut-out detail and big black sunglasses that gave her a Terminator-style appearance.

One of a kind: Madonna was her usual edgy self as she strutted through New York's JFK airport on Monday night clad all in black

Chunky boots, baggy black pants with large grey pockets, a top, scarf and jacket with crazy zipper detail all over was her outfit of choice, while she toted her own heavy-looking black handbag as she exited her chauffeur-driven SUV.

She wore her long blonde locks back in a pretty low bun and minimal make-up as she embarked on her flight solo.

Earlier that day, the Material Girl posted a photo in a similar all-black ensemble, though this one had somewhat of a dominatrix-style about it.

The singer posed in an elaborately ornate bathroom dressed in a black dress with shoulder and neck detail and wearing the same sunglasses and gloves, with the caption: '#secretprojectrevolution coming soon to BRAZIL! Get ready!'
